TAILIEUCHUNG - Auto control for Commercial building
This section describes heating, ventilating, and air conditioning (HVAC) systems and discusses characteristics and components of automatic control systems. Cross-references are made to sections that provide more detailed information. A correctly designed HVAC control system can provide a comfortable environment for occupants, optimize energy cost and consumption, improve employee productivity, facilitate efficient manufacturing, control smoke in the event of a fire, and support the operation of computer and telecommunications equipment | HONEYWELL Engineering Manual of CONTROL for Commercial Buildings 1J J J JJ J i J J1 i J J 1 JI j IJ J H 1 J1J JI JJJJI JJIJlJjjJHlJJlHJllJJIJllill I j j I i u j j I j ri j n j 1 j I 11F Mil h i 111 j i j h j j j I j i- Copyright 1934 1940 1953 1988 1991 and 1997 by Honeywell Inc.

The manual quickly became the standard textbook for the commercial building controls industry. Subsequent editions have enjoyed even greater success in colleges universities and contractor and consulting engineering offices throughout the world. Since the original 1934 edition the building control industry has experienced dramatic change and made tremendous advances in equipment system design and application. In this edition microprocessor controls are shown in most of the control applications rather than pneumatic electric or electronic to reflect the trends in industry today. Consideration of configuration functionality and integration plays a significant role in the design of building control systems. Through the years Honeywell has been dedicated to assisting consulting engineers and architects in the application of automatic controls to heating ventilating and air conditioning .
